Minecraft Servers are down?

I just tried to play on Minecraft, and the button at the login screen that usually says 'play' said 'play offline' I can get on google fine and surf the web. Xbox Live is working as well. When I finally got it to say just 'play' (after a minute of waiting because MC was also being unusually slow) I tried to join multiple server but when I was login into them, it said something about the authent-(I don't know the rest of the word lol) something like that. I also tried logging out then logging back in, but when I tried to log back in, MC said,"Sorry our servers are down right now please try again later. We're working on the problem." Anyways, how do i fix this? I have tried restarting the computer and re-downloading the MC launcher.
